Fundamental Aspects of Acoustic Emission Applications to the Problems Caused by Corrosion


This paper describes the utility of acoustic emission (AE) for the detection and monitoring of corrosion, stress corrosion cracking (SCC), and corrosion fatigue (CF). It comprehensively surveys laboratory studies and field applications that have been made to date. How to apply the technique to fundamental studies in the laboratory and continuous monitoring in engineering structures are discussed in detail. Various microprocesses that can produce detectable AE are shown and their relative energy levels, emanated as AE, are discussed in terms of peak amplitudes measured on laboratory specimens by a conventional piezoelectric sensor. All the available information clearly demonstrates the potential usefulness of the AE technique.
